Generalized transport analysis on mixed convection squeeze flow of a Casson fluid over an inclined stretching sheet with viscous dissipation and double stratification

Abstract

The utility of squeezingly driven stretching movement of non-Newtonian liquid to enhance the mechanical efficiency of a industrial processes, such as, extraction crude oil, cooling process of nuclear reactors, food processes, electronic chips manufacturing, pollution of ground water, fabrication of plastic materials, etc., is diverse. This inspires us to describe the mathematical stimulation of squeezed fluid flow via stretchable inclined wall. The non-Newtonian Casson fluid model is utilized here. The investigation related to heat and mass transport is pursued under the Cattaneo-Christov theory. Additionally, viscous dissipation and double stratification phenomena are also incorporated in the analysis of heat and mass transport. The governing equations are transformed under the appropriate variables. The convergent analytical solutions are acquired through homotopic technique. To notice the remarkable impacts of notable parameters on flow fields and skin friction coefficient, graphs have been plotted in two-dimensional axes. The values used for involved parameters are λh=Pr=λc=Sq=1.2,δ=ε=ε1=0.1,Gh=Gc=0.3,α=π/4,Re=0.2,β=1.0. The results depict that the dissipative effect increments the temperature distribution. Casson fluid parameter has decrementing impact in velocity field near the plates while opposite trend is witnessed apart from the plates. The current analysis incorporates numerous industrial and technological processes including pharmaceutical, petroleum related industries, marine engineering, nuclear up and down processes, etc.
